Other claims from this paper (14)
- Observation Digestate media initially had high ammonium concentrations.
- Observation Available ammonium declined to about half after ten days and nearly completely by the end of cultivation.
- Observation Available nitrate began at 0–8 mg/L across treatments.
- Observation Available nitrate fell to zero within a week.
- Observation Available nitrate increased slightly from day 40.
- Intervention effect Nutrient use efficiency was generally higher with 19 % digestate.
- Intervention effect Sawdust inclusion reduced nutrient use efficiency by 30–50 %.
- Intervention effect Tomato biomass with 37 % SAD was 62 % of the mineral fertilizer reference.
- Intervention effect Tomato biomass with 19 % SAD was 47 % of the mineral fertilizer reference.
- Intervention effect Harvestable fruit yield was similarly reduced in digestate treatments versus the reference.
- Intervention effect Chlorophyll fluorescence indicated elevated plant stress with SAD fertilization.
- Intervention effect Sawdust addition did not help control nitrogen availability during cultivation.
- Intervention effect Nitrifying bacteria addition did not help control nitrogen availability during cultivation.
- Recommendation The authors recommend further optimization of anaerobic digestate fertilizers before competing with mineral fertilizers.
